The Yakovlev Yak-44 (Template:Lang-ru) was a proposed twin-turboprop Airborne Early Warning (AEW) aircraft, resembling the United States Navy's E-2 Hawkeye, intended for use with the Soviet Navy's Ulyanovsk class supercarriers. Along with the aircraft carrier it would have flown from, the Yak-44 was cancelled after the demise of the Soviet Union. A full-scale mockup with foldable wings was built.
Design and development
In the late 1970s, the Soviet Navy adopted a plan to build large aircraft carriers capable of operating conventional aircraft rather than the VSTOL Yakovlev Yak-38s operated by the existing Kiev class aircraft carriers. These new carriers required a shipborne airborne early warning (AEW) aircraft to be effective, and the Yakovlev design bureau was instructed to develop such an aircraft in 1979.[1][2] While the AEW would be the primary role for the aircraft, it was also planned to develop versions to serve in the anti-submarine warfare (ASW) and carrier on-board delivery (COD) roles.[2][3]
The basic layout and size of the final Yak-44E design was similar to that of the Grumman E-2C which operated in the same role from American aircraft carriers, being a twin-engined high-wing monoplane with a rotating radar dome (rotodome) above the aircraft's fuselage. The Yak-44 was designed to carry much more fuel, and was therefore far heavier.[2][3] The engines were to be two Progress D-27 propfans rated at 14,000 ehp (10,290 kW) each, driving contra-rotating propellers. The crew of five were to be accommodated in a pressurized fuselage, while the aircraft's rotodome, carrying a NPO Vega pulse-doppler radar could be retracted to reduce the aircraft's height when stowed below decks in the carrier's hangar. The aircraft's wings also folded upwards, while a twin tail was fitted.[2][4]
The aircraft was stressed to allow catapult launching and arrested landings, but was also capable of operating from the ski-jump ramps of the Project 1143.5 carriers (later to become known as the Admiral Kuznetsov class).[5]
A detailed full-size mockup was completed in 1991, and approved with minor changes by the Soviet Naval Aviation (A-VMF). The collapse of the Soviet Union in 1991 resulted in the program being delayed, with the catapult-equipped Ulyanovsk being cancelled and scrapped, and the second Admiral Kuznetsov class carrier, the Varyag, being left incomplete. The Yak-44 program was abandoned by the Russian Navy in 1993.[5][6][7]
